In June 2003 a new unofficial patch has been made available to fix many of the problems with MM9. It appears to solve all issues which were patched before by KKC and Klar (see below), plus many more. (Because I'm not playing the game anymore, I haven't tested it, but it appears very thorough.) Get the patch at Telp's patch page.
KKC, collaborating with Flamestryke (take a look at her site; it's in the links section),
has fixed a number of scripting errors with the quests in the game. My thanks to them
for picking up where 3DO left.
Since the list of changes contains spoilers, it is at the bottom of this page.
All changes are done to one file: MM9\data\RUDE.REZ. The zip file below contains just that file, so you'll have to make a backup of the original RUDE.REZ file, and then unzip the new file into the data directory. (It might be safest to do this while the game is not running.)
Note: this patch is for the English (US) version only!
If in any way the patch doesn't work for you, just restore your backup of the RUDE.REZ file.
There is also a temporary fix for the bug with the
disappearing writ in Verhoffin's Ruins.
Use this fix only
when you've fallen victim to this bug, and restore the previous situation
afterwards. If you have trouble downloading this fix there, you can also get it
here. Make sure you've read the instructions though.
Thanks to Klaravoyia, for supplying a solution for people caught by this bug, who now don't need to start all over, after playing the game two thirds through.
And finally a disclaimer: these patches are in no way related to 3DO or New World Computing, and installing them is at your own risk. However I believe the patches were made with good intentions, and my game still worked after installing them (haven't tried all the quests yet, but the bathhouse neatly cleared for me). I detected no viruses either, but feel free to check for yourself: better safe than sorry ;)
